WL/XL flywheels are narrower than Indian
flywheels, but there are ways of making up for this in connection with
the thrust washers either side of the wheels. I suggest using a special
IPE thrust washer adapter (P/N TWAWL) for some applications. The
thrust washer/ adapter thing can be a little confusing, but I hope this
table will help. You must of course use the correct thickness thrust washers
to get the correct end play on the crank assy, but this part of the job
is just like building an engine with stock flywheels. Any questions, just
ask! If you are a machinist, you can probably devise a way to bypass most
of this and come up with your own thrust washer arrangement.
27B174
is the stock Indian flywheel thrust washer for Chief and 45" 101. Available
in various thicknesses for setting the end float.

has Parts for these Stroker Setups:
101 (37" G and 45" GP) with WL flywheels and rods. 741 and Sport Scout with WL flywheels and rods. 741 and Sport Scout with XL flywheels and rods.

There are other ways of making 741s faster (cheaper and maybe a bit easier, but not as all-out, old-school cool as a stroker!). Big bore pistons and big valves help a lot. See the 741 parts page. IPE Electronic Ignition is a big help for any Indian, not least a tuned - or stroked - one, where bad ignition timing may have more serious consequences. Good examples of pretty powerful stock-stroke 741s here and here. | |

Stroker 101 with WL flywheels (750 cc). To build a 45"/750cc 101/WL stroker from a 37"/600 cc engine, you will need the major parts below. Click here for a complete list of all parts needed. 1) Used WL flywheels. See notes on second-hand Harley parts below. 2) New WL crankpin and big end assy. Get these from a reputable supplier of Harley parts. I will see if I can't find a way to start having these parts in stock in the future, so you can get everything you need here. 3) Used WL rods. See notes on second-hand Harley parts below. 4) IPE Stroker pinion shaft, P/N 28B53WL. 5) IPE Stroker drive shaft, P/N 20B96WL. 6) IPE thrust washer adapters, P/N TWAWL - you will need two of these. 7) IPE Stroker Pistons, P/N 75494S. Note that these pistons have a 4 mm (approximately) "pop-up" like the factory Bonneville pistons, and need the cylinder heads to be cut out for this.

Picture shows stroker piston pop-up at TDC like on factory Bonneville pistons. Heads must be relieved for this. This applies to stroker pistons for 37"/600cc Scouts and 741 (741 cylinders will have to be bored to 600cc size ~ 70mm to use these pistons). These engines will end up as 45"/750cc. Never mind the funny manifold nipple on this cylinder; just another experiment... |

101 with WL flywheels (811 cc).
To build a 50"/811cc 101/WL stroker from a 45"/750 cc engine, you will need the major parts below. Click here for a complete list of all parts needed. 1) Used WL flywheels. See notes on second-hand Harley parts below. 2) Used WL rods. See notes on second-hand Harley parts below. 3) New WL crankpin and big end assy. See note above. 4) IPE Stroker pinion shaft, P/N 28B53WL. 5) IPE Stroker drive shaft, P/N 20B96WL. 6) IPE thrust washer adapters, P/N TWAWL - you will need two of these. 7) IPE Stroker Pistons, P/N 27C121S. No "pop-up" on these pistons so cylinder heads do not need modification.

Stroker 741. This engine has one of the prototype manifolds, seen on the 741 page, and big nipples to match. |

| Stroker
741 with XL flywheels (750 cc).
To build a 45"/750cc 741/XL stroker, you will need the major parts below. Click here for a complete list of all parts needed. 1) Used XL flywheels. See notes on second-hand Harley parts below. 2) New XL crankpin and big end assy (if you go with used rods). 3a) Used XL rods. See notes on second-hand Harley parts below. Alternative: 3b) New XL rod and big end assembly. Complete rod and big end assembly. The way to go for most stroker builders, as you probably can't rebuild a set of used rods for the same price unless you do all the work yourself. 4) IPE Stroker pinion shaft, P/N 39348XL. 5) IPE Stroker drive shaft, P/N 41044XL. 6) IPE Special pinion housing, longer and allowing for line honing of the main bearing housings (small lip around timing side crank case must be removed for this). We need to talk about the size of the bearing bore in your cam side crank case after it has been honed round. The OD of the pinion housings is finish ground to measure. P/N 20B101XL. 7) IPE Stroker Pistons, P/N 75494S. Note that these pistons have a 4 mm (approximately) "pop-up" like the factory Bonneville pistons, and need the cylinder heads to be cut out for this.

Complete XL rod kit. New rods with honed races and pin bushings, crankpin, rollers, roller cages and nuts. |

on second-hand Harley parts. Updated
with new info May 17, 2009
WL flywheels. Sorry, I can't help with these but, as 88,000+ sets were made, it should be possible to find one almost anywhere in the world. Make sure the tapers for the shafts are good. XL flywheels. 900 or 1000cc "Ironhead" Sportster, 1957 to early 1981. Jeff Diamond of Victory Library (see link in right column) pointed out to me that the tapers for the shafts in Sportster flywheels changed in late 1981. So watch this point when hunting wheels. Sorry, I can't help with these either, but you should be able to find a set almost anywhere in the world. Make sure the tapers for the shafts are good. To convert for Scout use, you must lathe cut the stock thrust washer recesses on the outside flywheel faces to take Indian 27B174 thrust washers + you must use a slightly longer IPE pinion housing to make up for the narrower width of the XL flywheel assy. Housing bore is also bigger than stock to take the fatter pinion shaft. WL rods. I can occasionally supply these, but you should be able to find a cheap set where you find the flywheels. Be aware that these rods invariably will need straightening before use (they are often both bent and twisted), as well as the usual honing back to round before new races are sized on the OD, pressed in to the correct depth and finish honed. New pin bushings must also usually be fitted and sized. XL rods. Same as above. A new XL rod kit from IPE is probably a better and cheaper alternative for most people. Jeff also pointed out that there are different lengths of Sportster rods, which allow more choices of compression distance, rod ratio, cylinder height and pop-up. There is a chart of Harley rod lenghts here. |
Victory
Library
There is a ton of good info here - including The Linkert Book. If you are interested in how your Linkert works in detail, in making it give its best, and maybe even in going beyond that, GET this book if you don't already have it. Lots of other interesting books on the Victory Library site. Jeff is one of my heroes for his commitment to getting to the the bottom of what makes our old junk tick, and for his willingness to share the results of his research.
